Privacy Policy
The short version: your images never leave your device, and we do not ask you for an account. Below is the detail.
Last updated: 31 July 2026
Your images are never uploaded
Every tool on this site runs entirely in your browser using the HTML Canvas API. When you select files, they are read from your disk into your browser's memory, processed there, and written back out as a download. At no point is an image sent to us or to anyone else.
You can confirm this yourself. Open your browser's developer tools, switch to the Network tab, and process a batch: there are no upload requests. You can also disconnect from the internet once the page has loaded and keep working.
What we do not collect
- No images, filenames or image metadata.
- No accounts, email addresses or passwords.
- No image processing history.
What is stored on your device
We use your browser's localStorage to remember preferences so you do not have to set
them again. This data stays on your device, is never transmitted, and can be cleared at any time
through your browser settings. It covers:
- Light or dark theme.
- Selected language and tool mode.
- Output format and quality.
- Watermark settings, including a small logo image if you added one.
Analytics and advertising
The site may use privacy-respecting analytics to count page views, and displays clearly labelled advertising. Advertising partners may set their own cookies or use similar technologies to measure and target ads, governed by their own privacy policies. None of these have access to your images, because your images are never transmitted.
You can block advertising and analytics with a content blocker; the tools will continue to work normally.
Third-party resources
When you download a batch as a ZIP, the browser fetches two open-source libraries (JSZip and FileSaver.js) from the jsDelivr CDN at that moment. This request reveals your IP address to jsDelivr, as any web request does. It contains no image data. If you never create a ZIP, the request is never made.
Children's privacy
The site is not directed at children under 13 and we do not knowingly collect personal information from anyone.
Your rights
Because we hold no personal data about you, there is nothing for us to export, correct or delete. Preferences stored on your device are under your control and can be cleared from your browser at any time.
